Abstract
Exemplary embodiments are disclosed of a control for an HVAC system. The control has an alphanumeric display, a plurality of two position switches (e.g., push buttons, etc.), and a processor. The processor receives a current user input through at least one of the two position switches and determines a response to the current user input. The determining is performed using one or more previously received user inputs, if any, via one or more of the two position switches. The processor implements the determined response by displaying a message on the alphanumeric display and/or changing an operational parameter of the HVAC system.
